Just got myself two Gainward GTX 580s and running them in SLI... These bad boys get HOT! I have dropped the clocks a little to give me a few degrees less but I am having to use a desk fan to cool then at the moment as without they hit the die point of about 98c then just crashes out... with the fan i can get away with it. Problem is though is there not going to last long at these temperature really... They are cooking Any tips on what i could do to try getting them down abit?
